I am very interested in getting a Lyman Great Plains Rifle for hunting and recreational shooting. I am looking at the left hand .54 caliber flint lock model. I was just wondering your alls opinion on this weapon and some loads that might be best for it.
 
I have a GPR 54 cal percussion. I've shot loads as high as 120 grains FF with a PRB and TOTW Mink Oil lube with decent accuracy. That load let's you know it's there! Regularly shoot 85 grains FF and a prb with good accuracy. This gun will stop anything you feel like standing up to. :hatsoff:
 
Welcome to the forum! Stick around, these guys know their stuff. You've pick a good camp fire to visit.

This is a big subject, try the search feature. There are many topics on the GPR.

Many here own them and love them. Most will agree that you can't go wrong with the GPR.

To help you alittle, .54 seems to be the most preferred, and it is my choice. Search the hunting forum to find hunting loads (many GPR mentioned). But the load really comes down to what your rifle likes. There is also a formula to figure out the starting load, but I can never remember it. I just start off with 60 grains of BP for a .54 cal.
In my .50 I start with 55 gr. work you loads up in 5 gr inciments and find the sweet spot. My hunting load is 90 grs BP with a .018 patch and .530 ball. Also try a couple different ball and patch combos. :yakyak:

Like I said try the search, you'll find a ton o' stuff. enjoy :grin:
 
The GPR is a well built, reliable and accurate gun. You can't do much better in that price range. A good hunting load in mine runs 80-90 grains, and I get fine accuracy with lighter charged. .54 is a good choice for overall versatility. I think you'll like the gun! Let us know how it shoots! :)
 
The .54 flintlock has to be the best bang for the buck I have found yet. I have built several from kits and think that is the best way to go.

You will need some sandpaper, an exacto knife, a bottle of LMF browning agent, and a jug tru-oil
some basic hand tools and a little patience.

Even as a rookie I think the kit is the way to go.

You can build it on the kitchen table, sand it on the porch and brown it in the bathroom, (might want to check with the little woman first).

I like the idea of the kit CUZ it slows you down and lets you get to know your rifle. I think you just get off to a better start than ordering everything you need at one wack heading to the range and make smoke.

Take your time build the kit, do the research, put at least 6 HAND RUBBED coats of true oil on her ,get to know your rifle.

Then when you go and shoot her the first time you
have a friend with you instead of a stranger.

Just my 2c.
 
Welcome to the forum! :hatsoff:

I love my .54 GPR flinter! I use 80 grains 3f, pillow ticking, bore butter, and a .530 roundball. And a few grains of 3f in the pan too.
 
Welcome to the forum..
I have a left hand 54 cal. GPR it likes 90 gr. of 3f swiss and I prim with 3f swiss.
I put the Lyman peep sight on it and it shoots as well as I can shoot any rifle off hand. :winking: Rocky
 
I have had a .54 GPR flint for a couple of years. Wonderful rifle. Reliable and a straight shooter.

Just be sure you clean it real good, twice, before you start shooting. I used modern chemicals for the first cleanings to rid the factory protection. Then use the hot water/butter from then on.

Good luck
 
Got one and really like it.
.535 RB
100grs FFg Goex
.020 pillow
Stumpy Moose Milk lube
Getting all but one hole at 50 yds.The .530 RB opens up a little to 1 1/2-2" groups.Good hunting accuracy.
 
I bought a GPR because of this forums recommendation and couldn't be any happier with it. Great gun and the more you shoot it the better it gets in regards to shooting tight groups. Right out of the box my rifle was shooting decent groups but the more it got broken in the tighter the groups.

I already owned a caplock GPR(.50), it was so accurate and great to shoot that I recently aquired a flintlock version with a .50 and .54 1:60 twist barrels.The friend that I buy 25lb cases of powder with said our new shipment just arrived, it contains some 4f for priming and I am ready! I can't wait to start shooting some flintlock :grin:
 
Probably one of the best buys for the money and follows the lines of the originals pretty well also, I would still have mine if a guy hadn't wanted to trade straight across for a NW trade gun from a North Starr West kit....go figure, the trade gun just needed a little cosmetic help which did not take long.
 
Can anyone tell me what the distance is from the back of the barrel to the rear sight is on a GPR??

I just sold my .54 flint or I would measure myself.
 
Mine is 8 1/4 inches from the barrel seam at the tang to the rear of the dovetail. I do not have the rear sight installed at the moment as I have a tang sight installed instead.
